FOLDING CHAIR.

SPECIFICATION forming part of Letters Patent No. 451,475, dated May 5,1891.

Application filed June 12,1890. Serial No. 355,189. (No model.)

To @ZZ whom t may concern.-

Beit known that I, I-IEZEKIAH Fonsvrn, a citizen of the United States,residing at Detroit, county of Vayne, State of Michigan, have invented acertain new and useful Improvcmentin Folding-Chairs; andI declare thefollowing to be a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings,which form a part of Athis specification.

It is the object of my invention to produce a folding chair which shallbe useful as a lawn-chair, a camp-chair, a camp-cot, an invalids chair,and the like; and it consists in a combination of devices and applianceshereinafter described and claimed.

In the drawings, Figure l is a side elevation of mychair. Fig. 2 is aplan, and Fig. 3 is a view showing the chair suspended.

In carrying out the invention, E represents vthe main back pieces oruprights, at the top of which is across-piece E. To this crosspiece Ethe upper end of the canvas F is engaged.

G are upright pieces at the front of the chair,

their upper ends connected together' by the cross-round G and adjacentto the lower end they are connected together by the cross-piece G2. Thecanvas F,being engaged to the crosspiece E', extends down parallel withthe back pieces and outward to the upper ends of the uprights G,over thecross-piece G ,and down to the cross-piece G2, where it is rigidlyengaged.

H II are side pieces extending from the upper ends of the pieces G backto the upright back pieces E, where they are pivotally engaged, and Jare side pieces extending from the upright G, where they are pivvotedback to the lower ends of the upright back pieces E, where they are alsopivoted.

K L are diagonal uprights and constitute the supporting-fra1ne of thechair. The uprights L are pivoted at h to the part II and at m to thepart M, while the upright K is pivoted at h to the part II, but has itsfree upper end resting on L when the chair is open. Now, the parts beingpivoted together at y' j 3'2 js, it will be observed that when a personsits down in the chair and exerts a pressure on the back it will yield,and because of the pivotal engagement of the parts, as shown, the personmay assume any position from a horizontal to an upright that maybedesired.

In order that the parts may be held in the position desired, I providethe pieces M,pivot them to the upright base portion, as at m, extendthem back adjacent to the uprights E, and provide the pin e and notchesm', which notches, engaging on the pin, hold the chair in the positiondesired. A

Another important feature of my invention is the provision of astrengthening-frame loeneath the seat portion of the canvas-that is, theportion of the canvas where the greatest weight of the person comes whenthe back of the chair is in an upright position. N are pieces pivoted tothe pieces G. They extend back to a point adjacent to or beyond theupright pieces E, and are connected at the back by a suitablecross-piece N. Apiece of canvas is attached to the cross-piece G and tothe cross-piece N at the rear ends of the pieces N. P is a piece, therebeing one for eachHside, pivotally engaged at p to the piece N andprovided in the lower end with a slot p', adapted to engage over the pinp2 on the piece J. Now, as will be seen, as the upright back portion Eassumes a vertical position this re-enforcing frame will be forced up toa point underneath the seating portion of the main canvas and will actto support the canvas at this point and thus prevent the main canvasfrom sagging down.

If desired, there may be provided a foot piece or frame Q, pivotallyengaged to the lower ends of the piece G.

When the chair is suspended, as in Fig. 3, I first fold up the leg orbase portion to the position shown, and then pass the suspendingcordfrom the ends of the pieces K and the pieces H, as shown.

W'hat I claim isl. In a folding chair, the combination of the followingelements: the pieces E, G, H, and J, pivotally engaged together, asshown, and engaged to a corresponding set of pieces by the cross lpiecesG G2, and E', a supportand the notched bars M for holding' the e'nnir:md hearing' on pins p2 on the pieces J, sui)- in position,snbstzmtfizdiy LS deseribed. stantizrliy as described.
